Emphasis on functional programming model

As mentioned in the previous release blogs, with this release we are shifting to a simpler functional programming model.

In the nutshell a simple spring-boot application with at least one function bean is also a spring…

If you listened to Oleg Zhurakousky's talk at Spring One Platform 2019 about Spring Cloud Stream & Functions or read his recent blog posts about Simplified Spring Cloud Stream and Functional Spring Cloud Stream, you may want to say: "Wait! What happened with Spring Integration support? What do I now do with my @ServiceActivator or IntegrationFlow? I used to deal with the Sink.input() as a channel to consume binder destination with some Spring Integration logic!" As Oleg mentions in his blog post, it is still possible with existing @EnableBinding and so on, but we are moving away from that…

Hi, Spring fans! In this installment, Josh Long (@starbuxman) talks to Apache Tomcat, Netty and Spring Framework engineer Violeta Georgieva (@violeta_g_g).

Hi, Spring fans! What a week! I've just returned from Prague, the Czech Republic, where I was for the epic Geecon Prague 2019 event. (Thanks for voting my talk on Reactive Spring the #1 talk, Prague!). Now I'm in Nantes, France, the DevFest Nantes show. I'd never been to Prague and I've never been to Nantes. So how's that for cool first-time appearances in one week? I'll be speaking about testing here. Tonight I fly to Paris, Fr, for customer meetings. Then I fly on Thursday to St. Petersburg, Russia, for the Joker conference, where I'll be presenting on testing and I'll be co-presenting with…

Last year right in the middle of SpringOne Platform 2018, I posted the first post in this series, _ The Reactive Revolution at SpringOne Platform 2018 (part 1/N)_, which looked at some of the big features we'd just dropped at SpringOne Platform 2018. I wanted to follow up and revisit that blog and the concepts I'd introduced last year, and show just how far we've come in the intervening year. TL;DR: things are much easier!

R2DBC

Last year, we announced our work on trying to support a standard for reactive SQL data access with a new project called R2DBC. Traditional approaches to SQL data…

Hi, Spring fans! Welcome to another installment of a Bootiful Podcast! In this week's installment Josh Long (@starbuxman) talks to Rafael Winterhalter (@rafaelcodes) about Bytebuddy; Mockito; the JVM; bytecode; Oslo, Norway; and so much more.

• Mockito
• JavaZone

In the previous post, I tried to provide justification for our shift to a functional programming model in Spring Cloud Stream (SCSt). It's less code, less configuration. Most importantly, though, your code is completely decoupled and independent from the internals of SCSt.

In this post, I’ll dig a little deeper and summarize the core features of our functional support, specifically around its reactive features.

IMPORTANT: Anything you can do with @StreamListener/@EnableBinding you can also do without it. In other words, the functional support is now feature-compatible with the annotation-based support.

Hi, Spring fans! WHEW! What a week! Last week was the insane SpringOne Platform 2019 event, from which I am still recovering! Then I flew home, hosted Spring team member and Micrometer lead and friend Tommy Ludwig in San Francisco, and prepared to fly out for meetings and user group appearances on Monday (in Stuttgart, Germany) and Tuesday (in Amsterdam).

I prepared, and got into the Uber going to San Francisco airport when I got a call from my brother saying my 81-year-old dad wasn't doing well (thanks to everyone for the well-wishes!) and was rushed to the hospital. I had to, regretfully…
